Calathea roseopicta

Location and care

Calathea roseopicta is a demanding houseplant that needs plenty of moisture, warmth and light. It should be placed in a bright, but not directly sunny spot, otherwise the leaves may burn. The temperature should be between 23 and 25 degrees Celsius and should not fall below 18 degrees Celsius, even in winter. The humidity should be high, so a bathroom, kitchen or conservatory are suitable locations. To increase the humidity, the plant can be sprayed regularly or placed on a bowl of moist gravel.

The soil should always be moist, but not wet. It is advisable to use a peat-based or acidic potting soil that is well-drained and rich in nutrients. A drainage layer of expanded clay can prevent waterlogging. Calathea roseopicta should be fertilized every two weeks with a special fertilizer for houseplants, preferably during the growth phase from spring to autumn. The plant should be repotted in a larger pot every two to three years.

Propagation and pruning

Calathea roseopicta can be propagated by division. To do this, carefully remove the plant from the pot and cut the root ball into several parts with a sharp knife. Each part should have at least one leaf and some roots. The parts are then planted in new pots with fresh soil and watered well.

The plant does not need to be pruned, except to remove dead or damaged leaves. Care should be taken not to damage the midrib of the leaves, as this ensures the plant's water and nutrient supply.

Toxicity for dogs

Calathea roseopicta is unfortunately a poisonous plant for dogs. It contains saponins, which can cause irritation of the mouth, stomach and intestines if swallowed. Symptoms of poisoning include vomiting, diarrhea, salivation, loss of appetite and lethargy. In severe cases, convulsions or shortness of breath may also occur.
